* Remove unused conf_preseek from buffering.c and all of its accountraments. ↵Brandon Low2007-11-05
| | | | | | This is _not_ a setting. This is a guessing tool used by either playback or buffering to serve its clients better. Use the REBUFFER_GUESS size in resume to help obviate pondlife's bug. This will also need to be used when FS8092 gets fixed correctly with a complete rebuffer for backward movements.

Both make use of the fact that the first argument of the vector functions is longword aligned. * The ARM version is tailored for ARM7TDMI, and would slow down arm9 or higher.
